That energy is digging west in response to the pac ridge and it’s going to try to cut...but look at the blocking and confluence in its way and there is a lot of cold in front. Let’s see how this plays out...
 

The high should hold right? Thats why we pay big bucks for blocking

Primary goes into Wisconsin and there's still blue over our area, so probably lol

This run the block actually retrogrades so far SW (into central Canada) that it blocks the trough in the west from progressing east at all. So it ends up a crazy solution. A little less extreme and that system comes east under the block instead of cutting up west of it then occluding.

CMC ends up looking like GFS for next Thursday/Fri but warmer.  

That wave on the CMC on the 22nd isn’t the one the GFS amplifies. It gets squashed.  The cmc then suppressed the wave on the 24 that the GFS gives places north of DC snow. The wave on the 22 has no real chance if the trough splits our west.  The airmass isn’t cold enough yet.

That was a rare historic storm. Not here but it out down 40” in places and a huge area of 10”+. Your bar is ridiculous 

Yea but that storm happened before the pattern got amazing and it was waAY before peak climo

That was a pretty good pattern mid December that week.

Looked to me the NAO tries to link up with the SER which isn't crazy in this progression given the PAC. Remember, the PAC is running the show here essentially and if the ridge in the central PAC backs and pumps enough, then the SER naturally has a response to flex. Couple that with the retrograding NAO that attempts to link up and the pattern is teetering precariously on caving in on itself. Not saying this is right, but is certainly a viable solution given the progression in the PAC. You have been spot on discussion of the progression in the NAO, but we should be taking notes in recent times on how the PAC is dictating the conus pattern Moreso in recent years and what may have been gold just a few years ago has changed quite a bit. Again, not saying this is correct, but just something to consider.

ugh...that nothern vort killing what could have been a nice storm

Ya gotta hope that...we get at least 4 chances in our prime window. That way, if we continue contend with these stupid vorts hopefully one or two of the 4 a northern vort WON'T ruin things. It's like literal dice...do ya roll a vort or no? Lol

Putting on my Weather Will cap but.. PSU v2 storm looks ripe on the snow mean.. as good of a signal as you can get this far out

As for the 21/22 threat.. this isn't actually a disappointing mean. We're south of the center of the mean and the 850s are borderline, but we have blocking on our side at the very least. Glad we're dealing with a signal rather than a flicker so to speak.
